llYl PROVEMENT IN HEATlNG-STOVES.

Specification formingpart of Letters Patent No. 54,233, dated April 24,1866.

To all whom it may concern:

Be it known that I, WILLIAM VAN DE SANDE, of the city, county, and Stateof New York, have invented anew and useful Improvement in Coal-Stoves;and I do hereby declare the same is fully described and represented inthe following specification and the accompanyin g drawings, of which-Figure 1 is a perspective view of a stove with my invention applied toit. Fig. 2 is a "ertical section; Fig. 3, a horizontal section and Fig.4 represents a modification of my invention when used for heating theupper rooms of a dwelling-house.

This invention relates to a peculiar construction of a stove, in which amovable cylinder is placed within the outer drum or stove for receptionof the coal, and partially revolves on a pivot which is sustained by abrace attached to the outer drum at the top of the stove. This stove hasalso a grate which moves horizontally from side to side, the movementsof the said grate and movable cylinder being actuated at one and thesame time and in opposite directions by a lever connected with both, ten(1- ing thereby to remove the ashes from the cylinder and grate as wellas to prevent the adherence of calcined matter to either. The saidcylinder and grate can be easily removed from the stove when theyrequire cleaning.

Furthermore, by placing the inner cylinder at any desirable distancefrom the outer drum or casing, so as to leave a hot-air space between,(as shown in Fig. 4,) my invention can be used as a furnace for heatingthe upper rooms of a dwelling-house.

Having described the nature of my invention, I will now describe itsconstruction and mode of operation.

In the drawings, A represents the drum or outer cylinder; B, theash-box; O, the inner cylinder, with its arms D D and brace D. The braceD has a pivot, c, and nut or collar 6, said pivot being introducedthrough another brace, f, attached to the top of the outer casing, A,the latter brace sustaining the inner cylinder, 0, and permitting it torevolve on the pivot e.

The ash-box B has a slot, 9, in which the grate H slides freely fromside to side. A portion of the said grate projects in rear of the stovefor reception of a pin, 6, which holds the same in position during themovements of the grate.

The inner cylinder, 0, has a pin, 0, which plays in a slot, 0/, in theouter casin g, A. Said pin receives the bifurcated end k of a lever, L,whose fulcrum is attached to the'outer casing at m. The other end, 70,of the leverL has a journal, Z, which passes through a slot, n, in theash-boX B, and enters a corresponding hole in the grate H.

To operate my invention is merely to lay hold of the grate-handle o andmove the grate from side to side, whenmotion will be imparted throughthe lever L to the fire-pot or inner cylinder, 0, but in an oppositedirection in relation to the movements of the grate. The movements ofthe grate and cylinder, being reverse in relation to each other, tend tofree the burning coal from ashes, as well as to prevent the accumulationof calcined matter to the fire-pot or grate, either or both of which canbe removed from the stove for cleaning when desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The movable fire-pot orcylinder O, the lever L, and movable grate H,when, in combination with a coal-stove, A, operating in mannersubstantially as and for the purposes described.

In testimony whereof I have hereunto set my signature.

WM. VAN DE SANDE.
